This is a two-part article looking at factors impacting decisions on whether to use air or water-cooled air compressors. It also provides heat recovery guidelines for both situations. Part 2 will provide a review of alternative cooling water system options and their approximate operating costs.
An air compressor is synonymous with an electric heater – providing compressed air as a side effect. 85-90% of the electrical energy taken in by the air compressor is converted into heat, while the maximum efficiency of compressed air generation is less than 10%. In air compressor heat recovery systems, the focus is on capturing the heat energy contained in the oil, as up to 80% of the energy extracted from the power plant is found there.
To continue meeting demand for air compressors, Doosan Bobcat invested heavily in U.S. manufacturing facilities including its one-million-square-foot manufacturing operation in Statesville, North Carolina. The $70 million expansion of the facility amplified its operations, where it now employs 930 people in office and factory positions and manufactures its line of portable air compressors from 185 cfm to 1,600 cfm, in addition to other Bobcat products like compact tractors, generators, light towers and mini track loaders. It also assembles and stocks the expanding line of Doosan Bobcat industrial air compressors.
Over the last two decades, there has been a significant increase of manufacturing facilities deciding to produce their own nitrogen on-site, using compressed air systems and nitrogen generators. They are choosing on-site nitrogen generation, instead of purchasing and receiving deliveries of nitrogen by the cylinder or having a “Nitrogen Over the Fence” supplier.
“The AICD enjoyed a record turnout of exhibitors,” said Jeff Brennan, President, AICD. “We’ve added over 20 member companies this year and our membership again has delivered a strong turnout at this year’s event.” Participating distributor members and guests enjoyed a few days of networking events, trade show, speakers, the AICD Golf Tournament and more.
This is a two-part article looking at factors impacting decisions on whether to use air or water-cooled air compressors. It also provides heat recovery guidelines for both situations. Part 1 will provide a brief history on air compressor cooling, a review of cooling water sources and costs, and some cooling cost comparisons between air and water-cooled air compressors.
When Hitachi Industrial Equipment Systems Co., Ltd. (HIES) announced Sullair, Hitachi, and Champion Compressors (Australia) have come together under the umbrella of Hitachi Global Air Power (HGAP), many wondered what it would all mean.
In extreme situations, raw battery materials can react with water molecules in the air, causing explosions. In semiconductor development, wafer manufacture requires a highly controlled environment and precise data on the manufacturing environment. Moisture can cause defects in the microelectronic components, impacting their functionality and reliability. For each application, a fast response time allows for quick detection of dew point changes, which can be addressed before they cause damage to the product or equipment.
Aftermarket genuine parts ensure that the compressed air system will continue to meet the requirements it was engineered to achieve. Replacement parts must fit the compressor correctly so that operation continues to function properly. Parts that are not fitted properly could affect the function of the unit downstream.
The 2023 Hannover Messe was held April 17-21 at the Fairgrounds in Hannover, Germany. I have been visiting this event, since 1992, and it’s great to see old friends, new companies and the latest company and technology developments of firms in the compressed air industry. This article will provide readers with a sampling of compressed air technologies seen.
A focus on sustainable products and packaging, in combination with a passion for quality, has resulted in considerable growth for the firm. Plans to add production lines at facility #1, in turn, drove the need to address the plant’s faltering compressed air system.
